Comparison of body growth characteristics among models of breast cancer maintained on HFD

Parameter	Interpretation	FVB	PyMT	HER2	DMBA
Prepubertal phase
a₁	Weight at maximum growth rate, g	12.1 (0.12)^a	12.0 (0.18)^b	13.5 (1.6)^a,b	10.7 (0.45)^c
a₁ × b₁	Maximum growth rate, g/PND	0.681 (0.03)^b	0.721 (0.02)^a	0.761 (0.07)^a	0.729 (0.02)^a
d₁	Age at maximum growth rate, PND	21.3 (0.43)^a	17.6 (0.41)^b	20.5 (1.3)^a	16.7 (0.29)^b
Postpubertal phase
2a₁ + a₂	Weight at maximum growth rate, g			44.8 (23.9)^a	31.5 (0.5)^a
a₂ × b₂	Maximum growth rate, g/PND			0.0947 (0.07)^a	0.116 (0.01)^a
d₂	Age at maximum growth rate, PND			332.7 (233.7)^a	154.2 (5.8)^a

Values are means (±SE), with significant differences between breast cancer models that do not share a letter a, b, or c (P < 0.05). Parameters were estimated from monophasic and diphasic sigmoidal curves (27).
